Zeta Volantis, Latinized from ζ Volantis, is a binary star [6] system in the southern constellation of Volans. It has an apparent visual magnitude of 3.92, [2] which is bright enough to be seen with the naked eye. Based upon parallax measurements by the Gaia spacecraft, it is approximately 145 light-years (44.6 parsecs ) from the Sun. The companion is a magnitude 9.7 star at an angular separation of 16.7″ . [6] Based upon their motion through space, this system made its perihelion passage some 858,000 years ago when it came within 22 ly (6.6 pc) of the Sun. [7] It is currently moving away with a radial velocity of 48 km/s. [1]
The primary component is K-type giant star with a stellar classification of K0 III. [3] It has a derived luminosity of around 60 times that of the Sun, [1] 1.2 times the Sun's mass and is about 5.1 billion years old. At this age, it has expanded to 10.7 times the Sun's size. [2] The expanded outer envelope has an effective temperature of 4,788 K , [2] giving it the orange glow of a K-type star. [8]
